JetChip ECU upgrade?

[EricSol]

You have to remember that when I added my first piggyback ecu (Apexi Afc) I picked up 20 ft.lbs. of tq. at 3k rpm because I was sooo lean. I could see Jet being able to fatten the mixture explaining Greg's black lines down the street. In my opinion if you wanted to richen the mixture I would do it mechanically first via larger injectors, Jim's fuel pressure mod, bigger pump or a combo of the three. If I then wanted to control it I would go piggyback just for the sake of being able to adjust the a/f without having to send the ecu off. Its nice to be able to be on the dyno and with the push of a few keys or buttons dial in the mixture want.

For those who don't know I use the Split Second FTC-1 and the nice feature is the ability to pull timing (Cali only has 91 octane and I like my knock sensors to stay in one piece) as well as being able adjust your fuel.

I have the FTC 2..

8) I have the FTC 2..

Very funny, hehe

[Paladin06Greg]

Sorry, LOL

I should mention that I get my gas at station in Philadelphia, 94 Octane baby!!! Need I say more.. Hey you get what you pay for..

I would simply do it right. If you increase fuel, you need to therefore increase spark and air mixture too. Therefore, to safely do this without a chip is to buy bigger injectors, aftermarket ignition kit (spark), AFC (program air/fuel ratio), and to top all that with an air/fuel ratio gauge to make sure you are running stoich with the increase in fuel, air, spark. If you simply add bigger injectors, you are producing more fuel which is bad for the engine if you fine tuned that on the AFC with the addition of increased spark. We all know that the simple combination of fuel+ air + spark (combustion) is what an engine needs to produce. We manipulate all these factors to produce more hp. We add a K&N for more air into the engine, we add an ignition, plugs, and wires for better spark, we add a freer flowing exhaust for the combusted gases to escape freely for more effeiecient combustion. Just look at how an engine works and go from there. You can figure out how to get the most out of your engine once you learn the basics of how one works. If something sounds too good to be true, it usually is. That's all I have to say about the Jet Chip. I wouldn't touch it. You add all of the components I mentioned, I would guarantee as much hp as Jet does for their set-up, but this setup would actually work because you are physically changinging you air/fuel/ignition system.

I hear JET recommends doing it after your mods. If you did all the mods listed above, how much do you think the chip would increase?

Wow that should be added to a glossary on Solaraguy! Perfect example of getting more power! hehe

low resistance cold air would be tops for that k&n comment. (CAI)

If you already got a piggyback that can adjust fuel/air and timing then I don't think that a "Jet Chip" would do anything because you’re adjusting it anyway. Unless Jet does other manipulations for performance then it would not be worth it. They do however have the ability to remove the "governor speed control" I think if your not going to use a piggy back system i.e. greddy, apexi or other custom items like Ripp's black box then it would be ok.

It's on a case by case basis depending on what you want to do and how custom you want to go. There are dyno sheets that show results with just the "chip" alone so it does work.

Good explanation Mattyboyl.

He, he, he, he,LOL

That sounds a bit sarcastic solarat, but that's okay. If there is something you disagree with, state your case. I'm here to learn like anyone on here. I don't have a problem with that. I'm not a mechanic, but an enthusiast. I've had lots of work done to my 3000GT and took it to a speed shop where I learned alot about modifications and how they affect performance. It's basics that people are not getting. A Jet Chip takes the fun and basics out of the equation. Plus the methods I described are so basic that many people have been successful using it plus alot more with exhaust work, turbo/supercharger, ported/polished heads,downpipe, headers, etc. The Jet Chip on the other hand hasn't been successful for everyone.

Hey I was being for real dude. Not sarcastic

I liked your explanation, and belive it or not but there are people that don't get that consept and ask some crazy questions on this site and that would be a good point of reference.
I was just adding to what you said is all.

later dude!

Thanks man. This has been a very friendly forum, especially compared to the 3si.org which was a bunch of pompous know-it-alls that would flame you for just about anything you would say. This is Mr. Rodgers neighborhood compared to that forum which is why I like this bunch of guys. You guys listen to each other without arguing for the most part and offer some good ideas, praise, and just downright respect. It's a pleasure to come aborad such a forum with moderators that don't take crap on here and eliminate the problem before it gets out of hand. 3si.org com could learn from this board.

Yes alot of good people sharing good information. Here and Camryman, the only two place I go.
